Logistics and pretreatment of biomass fuels for gasification and combustion

摘要: Two aspects which are relevant for the conversion of biomass into electricity discussed: logistics supply, and pretreatment solid fuels at location plant. The costs logistic operations by truck, ship train have been calculated forest residues, wood waste from parks gardens, demolition wood, sewage sludge paper. results show that, Netherlands, transport truck is cheapest option in all cases. A price range 3.0 ECU/odt to 11.6 residues was found. on previously reported elsewhere. technology fuel has assessed. Based a literature survey inquiries manufacturers technical, economic environmental information gathered. considered are: storage site; size reduction; drying; briquetting pelletizing; feeding gasifiers. An evaluation system 30 MWe gasification plant made five fuels: fresh paper, sludge, verge grass wood. differences these result mainly heating value moisture content. found 1.4 MECU 11.4 wet sludge. 29 figs., 31 tabs., 23 refs.
